LinkedIn is hiring web developers. I'm posting this because I know that the market is kind of scarce.

Think about how screwed you'd be if you did not do well at LinkedIn. Imagine if for some reason they fire you. If they wanted to, they could ban you from having a LinkedIn account. This could have a serious impact on your career.

Do you honestly believe that LinkedIn is crucial to your career. You can make connections and contacts without participating in LinkedIn at all.

If LinkedIn was the end-all and be-all of proofessional networking, services like Monster.com and Dice.com would not exist. Nor would companies pay thousands to a sleazy headhunter to find them a "qualified" employee.

Saying "LinkedIn improves my career" is like saying "Facebook improves my social life". Facebook does not get your friends to hang out with you, but it does a very good job of creating the illusion that you have 120 "friends" who could hang out with you.
